BLNR or SubC Date, which one would you pick

[Gotgolf52]

Hello TRF.
I already have a SubC Date but my buddy want to exchage my SubC for his BLNR even trade. He doesn't care about the value of the watch, he is a diver and he could use the Sub more for his purpose. I am just a novice surfer, my Sub or his BLRN would suffice my use. The question is assume both are equally in price and condition, which one would you pick?
I like my SubC for the iconic history and no PCL
I like the BLNR because it more exotic and useful GMT timing. However, I am really torn.
